Feature request: New presentational fields (Line, Headline, Columns)

[iamlinkus]

How about a few new presentational fields?

Line (no props) - Just a simple <hr>, quick and easy, for content separation without impacting the data. You'd be surprised how useful this would be.

Headline (size could be a prop s/m/l or something like that)- Simple heading text (kind of how groups add a heading, but without the impact to the shape of the data).

Columns - We have the field "row", but all it does is put all fields, sized equally, into a row. Imagine you could divide the fields into columns, define the column widths using a ratio. Something like:

...
fields: [
 { 
  type: 'columns'
  columns: 
  [{
   width: '1/3',
   fields: [...]
   },
   {
   width: '2/3',
   fields: [...]
   }]
 }
]
...
